Just got mine today, thanks for the warning. It took over five minutes to start hashing after a reboot with my pool settings.
Yep the panel settings have been changed as noted above. But hashing at 11.6 ish.
we got a large batch in yesterday of the 12 Evens. Most work as advertised ( only one is 11.2 TH ) .
They definitely take longer to boot / mine , up to 20 Min of Uptime before mining, and I think it's due to the mixed Boards in the unit. They are clocking up / down to what they can work on, and I feel this is probably why they use BM Miner over CG Miner.
After a while the units work fine. You can no longer tinker with Freq.
